De Beer, Leon T.; Bianchi, Renzo
In the Maslach Burnout Inventory (MBI), burnout is conceptualized as a combination of emotional exhaustion, depersonalization, and personal accomplishment. However, the factorial structure for the MBI remains controversial. We examined the factorial structure of the MBI, relying on Bayesian structural equation modeling (BSEM). BSEM allows the investigator to take into account sources of influence such as approximately-zero factor cross-loadings and between-item residual covariances. Data from a convenience sample of 5,575 French teachers were mobilized. One-, two-, three-, and bi-factor models were tested using BSEM. Maximum likelihood (ML) estimation was also implemented to examine the robustness of the BSEM analysis. The BSEM analysis showed that a two-factor model, consisting of a burnout factor combining emotional exhaustion and depersonalization and a separate personal accomplishment factor, best fitted the data. ML estimation showed a substantial enhancement of model fit when information derived from the BSEM analysis was incorporated. The MBI appears to be underlain by a unified factor involving the emotional exhaustion and depersonalization items and a separate factor involving the personal accomplishment items. These findings are compatible with a research practice that involves combining the emotional exhaustion and depersonalization dimensions of burnout and considering personal accomplishment individually.

Over the past decades, cyber bullying has become the order of the day in the universities (schools), workplace and elsewhere. This growth involves inter-gender, and age demographics. The aim of this study is to explore and evaluate the extent in which literature studies covers female student's cyber bullying in South Africa. Although, cyber bullying exists against female students and it is so alarming and disturbing not only in South Africa, the problem has gained miniature academic study attention in the country. Cyber bullying occurs (at) anyplace where Internet connection or mobile phone network exist. This study highlighted the limited academic articles in South Africa that aims to focus on cyber bullying against female students. The finding also indicates that most of the published article focused on cyber bullying and bullying around the world, few mentioned girl child or female students. However, in the case of South Africa, cyber bullying on female students is limited in the discussed academic articles.

Chukwuere, Joshua Ebere; Chukwuere, Precious Chibuike
The impact of social media (SM) or new media (NM) in our education institutions and society today are undoubtedly overwhelming. Students in the developed and developing countries are becoming more addicted to social media and its applications for various reasons. These reasons can lead to change in social and personal lifestyle both academically and off-academic. This study aims to assess the impact of social media on female student's social lifestyle. The study deployed a quantitative research methodology involving questionnaire research instrument among 69 female students in the North-West University, South Africa. The findings include the followings; social media refines how female students think, interact, communicate, fall in love, their social lifestyle and many more.

The study employs the Box-Jenkins Methodology to forecast South African gold sales. For a resource economy like South Africa where metals and minerals account for a high proportion of GDP and export earnings, the decline in gold sales is very disturbing. Box-Jenkins time series technique was used to perform time series analysis of monthly gold sales for the period January 2000 to June 2013 with the following steps: model identification, model estimation, diagnostic checking and forecasting. Furthermore, the prediction accuracy is tested using mean absolute percentage error (MAPE). From the analysis, a seasonal ARIMA(4,1,4)x(0,1,1)12 was found to be the "best fit model" with an MAPE value of 11% indicating that the model is fit to be used to predict or forecast future gold sales for South Africa. In addition, the forecast values show that there will be a decrease in the overall gold sales for the first six months of 2014. It is hoped that the study will help the public and private sectors to understand the gold sales or output scenario and later plan the gold mining activities in South Africa. Furthermore, it is hoped that this research paper has demonstrated the significance of Box-Jenkins technique for this area of research and that they will be applied in the future.
